图1为本发明实施例提供的一种病理动画的自动生成方法的流程图，所述方法包括以下步骤S101～S103：Fig. 1 is a flowchart of a method for automatically generating pathological animation provided by an embodiment of the present invention, the method includes the following steps S101-S103:
S101：获取正常状态的第一网格图及病变状态的第二网格图；S101: Obtain the first grid map of the normal state and the second grid map of the lesion state;
可理解的是，所述网格图为将相邻的数据点用线段连接起来以形成网状曲面，其可以为三角网格图。It can be understood that the grid graph is a mesh surface formed by connecting adjacent data points with line segments, which may be a triangular grid graph.
S102：根据所述第一网格图及第二网格图确定所述第一网格图中存在位移的网格顶点；S102: Determine, according to the first grid graph and the second grid graph, grid vertices with displacement in the first grid graph;
可理解的是，为确定所述第一网格图中存在位移的网格顶点，可先确定所述第一网格图及第二网格图中各网格顶点的对应关系，再基于所述对应关系确定所述第一网格图中存在位移的网格顶点。It can be understood that, in order to determine the grid vertices with displacement in the first grid graph, the corresponding relationship between the grid vertices in the first grid graph and the second grid graph can be determined first, and then based on the Determine the grid vertices with displacement in the first grid graph based on the corresponding relationship.
在确定所述第一网格图及第二网格图中各网格顶点的对应关系时，可对比第一网格图及第二网格图，确定出相同顶点和不同顶点，再遍历所有相同顶点，找到所有相邻的不同顶点，然后根据这组顶点对相邻的不同顶点进行编号，再对已经编号的顶点的相邻顶点进行编号，依次循环遍历完所有顶点，从而确定出各网格顶点的对应关系。When determining the corresponding relationship of each grid vertex in the first grid graph and the second grid graph, the first grid graph and the second grid graph can be compared to determine the same vertices and different vertices, and then traverse all For the same vertex, find all the adjacent different vertices, and then number the adjacent different vertices according to this group of vertices, and then number the adjacent vertices of the numbered vertices, and cycle through all the vertices in order to determine the network The corresponding relationship of lattice vertices.
接着，将存在对应关系的第一网格顶点和第二网格顶点进行位置比较，在位置不同时，将该第一网格顶点作为所述第一网格图中存在位移的网格顶点。Next, compare the positions of the corresponding first grid vertex and the second grid vertex, and if the positions are different, use the first grid vertex as a grid vertex with displacement in the first grid graph.
S103：基于所述存在位移的网格顶点及预设动画时长生成病理动画。S103: Generate pathological animation based on the displaced mesh vertices and preset animation duration.
在具体实现中，在生成动画帧的函数被调用时，获取当前时间与所述病理动画起始帧之间的时间差，基于所述第一网格图中存在位移的网格顶点、时间差及所述预设动画时长生成动画帧，以生成病理动画，具体过程为：：In a specific implementation, when the function for generating animation frames is called, the time difference between the current time and the start frame of the pathological animation is obtained, based on the displaced grid vertices in the first grid graph, the time difference and the The preset animation duration is used to generate animation frames to generate pathological animation. The specific process is:
遍历所述第一网格图中存在位移的网格顶点，并将遍历到的网格顶点作为目标网格顶点；Traversing the grid vertices with displacement in the first grid graph, and using the traversed grid vertices as target grid vertices;
获取所述目标网格顶点的位移量；Obtain the displacement of the vertex of the target grid;
根据所述位移量、时间差及所述预设动画时长确定所述目标网格顶点的当前位置；determining the current position of the target grid vertex according to the displacement, the time difference and the preset animation duration;
例如：位移量为100个像素，预设动画时长为10s，时间差为0.3s，此时，即可计算0.3/10*100＝3，即对于目标网格顶点而言，其从第一网格图对应的初始位置向第二网格图对应的终点位置移动了3个像素，从而确定目标网格顶点的当前位置。For example: the displacement is 100 pixels, the preset animation duration is 10s, and the time difference is 0.3s. At this time, 0.3/10*100=3 can be calculated, that is, for the target grid vertex, it starts from the first grid The initial position corresponding to the graph moves 3 pixels to the end position corresponding to the second grid graph, so as to determine the current position of the target grid vertex.
根据所述目标网格顶点的当前位置调整所述第一网格图中对应的网格顶点，直至遍历结束后，将调整后的第一网格图作为生成的动画帧。Adjust the corresponding grid vertices in the first grid graph according to the current position of the target grid vertices until the traversal ends, and use the adjusted first grid graph as the generated animation frame.
可理解的是，由于第一网格图和第二网格图之间可能存在色阶差，因此，在步骤S101中，还可获取所述第一网格图和第二网格图的色阶差。It can be understood that, since there may be a color scale difference between the first grid image and the second grid image, in step S101, the color values of the first grid image and the second grid image may also be obtained. steps.
相应地，在步骤S103中，可基于所述色阶差、存在位移的网格顶点及预设动画时长生成病理动画。Correspondingly, in step S103, a pathological animation may be generated based on the color level difference, the mesh vertices with displacement and the preset animation duration.
具体过程与上述过程基本相同，不同之处在于：还需要确定病理动画的色阶，例如：预设动画时长为10s，时间差为0.3s，色阶差为20，此时，即可计算0.3/10*20＝0.6，此时，可将其从第一网格图对应的初始色阶向第二网格图对应的终点色阶调整0.6的色阶。The specific process is basically the same as the above process, the difference is that it is also necessary to determine the color scale of the pathological animation, for example: the preset animation duration is 10s, the time difference is 0.3s, and the color scale difference is 20. At this time, you can calculate 0.3/ 10*20=0.6, at this time, it can be adjusted by 0.6 from the initial color scale corresponding to the first grid diagram to the end color scale corresponding to the second grid diagram.
本实施例通过获取正常状态的第一网格图及病变状态的第二网格图，根据所述第一网格图及第二网格图确定所述第一网格图中存在位移的网格顶点，基于所述存在位移的网格顶点及预设动画时长生成病理动画，从而无需采用由技术人员制作病理动画，节省人力和时间。In this embodiment, by acquiring the first grid diagram in the normal state and the second grid diagram in the pathological state, determine the meshes with displacement in the first grid diagram according to the first grid diagram and the second grid diagram. Grid vertices, pathological animations are generated based on the displaced grid vertices and the preset animation duration, so that there is no need for technicians to make pathological animations, saving manpower and time.
